GETTING READY

MAKING
2. Cut the celery into very fine matchsticks and soak in iced water for at least 1 hour until curled.
3. Peel and cut the oranges so that only the segments between the membranes are left to use.
4. In a bowl put the segments with any leftover juice.
5. Cut the chicory into diagonal slices and toss with lemon juice.

SERVING
7. In a bowl add celery curls, orange segments and the watercress toss with the dressing and serve immediately.
